A. 4x -3x = 42
B. 3/4x = 42
C. 4x + 3x = 32
D.4/3x = 42

Answer 1

When you have numbers in a ratio, let's say, a to b, and you are looking for the numbers, use ax and bx.
You are given the ratio 4:3, so use 4x and 3x.
Then follow the directions.
If the sum is given, add 4x and 3x and set equal to the given sum.
